Description

Access door opening and closing control device, system and control method thereof

Technical Field

The present invention relates to an access door opening/closing control apparatus, system, and control method thereof, and more particularly, to an access door opening/closing control apparatus, system, and control method thereof, which transmits an access door opening/closing encrypted code provided only to authenticated female users to an access door opening/closing control apparatus provided in public restrooms through bluetooth, thereby opening an access door of a female restroom only in the case of female, and thus being capable of eliminating psychological uneasiness of female users who use public restrooms.

Background

Public restrooms for public use are installed in public places such as parks and squares, or ordinary buildings such as government offices, schools and companies, and a male restroom and a female restroom are usually operated separately for common use by unspecified persons.

However, as shown in fig. 1, since such public restrooms belong to facilities that are not available to a large number of persons, the entrance/exit door 10 is normally operated in an open state for 24 hours, and thus there is a problem in that there is no suitable method to prevent the male from unauthorized entrance/exit into/from the female restrooms.

In the rare time of the morning and the like, a male is immersed in a female toilet such as a park, a school, a broadcasting station, and the like, and crimes are being made on the female as a target, or crimes such as illegally photographed images are being dispersed by providing a peeping camera or the like are continuously increasing, so that the sense of uneasiness of the female using the public toilet is also increasing. Recently, with the gradual miniaturization of a candid camera, a hiding technology is gradually developed, and the female who uses a public washroom is increasingly uncomfortable.

If a camera is found in a female washroom or the like, a surrounding closed-circuit television monitoring system (CCTV: closed Circuit Television) camera is used to identify a suspected person and track and apprehend the person, but this is merely a post-measure, and thus is insufficient to eliminate the sense of uneasiness of women using a public washroom.

Accordingly, the opening and closing of the access door is controlled based on the sex of users who want to access public restrooms installed in public places such as parks, squares, etc., or general buildings such as government offices, schools, companies, etc., thereby fundamentally preventing men from accessing female restrooms, and thus, new access door opening and closing control devices and systems for enabling women to use public facilities in a more comfortable state when using public restrooms, and demands for such access door opening and closing control methods are increasing.

In the following description, a device, a system, and a method applied to a female toilet installed in a public place such as a park, a square, or the like will be referred to as a "first embodiment", and a device, a system, and a method applied to a female toilet in a general building such as a government agency, a school, a company, or the like will be referred to as a "second embodiment".

Fig. 2a is a block diagram of an access door opening and closing control system 1000 according to a first embodiment of the present invention. As shown in fig. 2a, the access door opening and closing control system 1000 according to the first embodiment of the present invention is configured to include a first access door opening and closing control device 100a, an integrated information center 200, a user terminal 300, a communication network 400, an access door 500, an application operation server 600, and the like.

For reference, in the following description, a public female restroom is exemplarily described as a public facility to which the access door opening/closing control apparatuses 100a and 100b and the access door opening/closing control systems 1000 and 1000 'according to an embodiment of the present invention are applied, but it is apparent that the access door opening/closing control apparatuses 100a and 100b and the access door opening/closing control systems 1000 and 1000' according to the present invention can be similarly applied to any public facility (for example, other public facilities such as a public nursing room and a public female dressing room) in which only female access is permitted and male access is strictly prohibited.

Alternatively, the access door opening/closing control apparatuses 100a, 100b and the access door opening/closing control systems 1000, 1000' according to the present invention may be applied to public facilities that allow only male access and strictly prohibit female access, and may be realized by, for example, setting a secret code included in an access door opening encryption code differently according to sex, or designating a sex code as male.

The first access door opening and closing control apparatus 100a may be disposed at the access door 500 of a public facility (e.g., a public female toilet, etc.) or disposed adjacent to the access door 500, so that the opening and closing of the access door may be controlled according to the reading result of the access door opening encryption code 30 (refer to fig. 5). For example, the first access door opening and closing control apparatus 100a according to the first embodiment of the present invention may have an internet protocol (IP: internet protocol) address in a digital manner and may operate using a stock power supply.

Further, the first access door opening and closing control apparatus 100a may be disposed at an appropriate position with respect to the access door 500 for the user's use, for example, may be disposed approximately at the height of the chest of an adult, or a step may be additionally disposed at the ground below the first access door opening and closing control apparatus 100a for the use of a child. Alternatively, the first access door opening/closing control device 100a may be provided so as to be coupled to a sliding device such as a rail and capable of sliding movement in the up-down direction, or may be implemented so as to judge whether a user approaching the access door 500 is an adult or a child by a sensor device (not shown), and then automatically adjust the height thereof by sliding movement in the up-down direction based on the judgment result thereof.

Further, the first access door opening and closing control apparatus 100a may be coupled with the integrated information center 200 through the communication network 400, more specifically, may be communicably coupled with the access door control and operation management server 210, thereby receiving the access door opening encryption code 30 transmitted in a bluetooth manner from the user terminal 300, and controlling the opening and closing of the access door 500 based on the identification of the received access door opening encryption code 30 and according to the access door opening and closing control command generated by the integrated information center 200. The specific operation, steps, etc. of opening or closing the access door 500 according to the authentication of the access door opening encryption code 30 will be described in more detail below.

As shown in fig. 2a, the first access door opening and closing control apparatus 100a according to the first embodiment of the present invention is constructed to include a main body 110, a camera 120, a bluetooth module 130, a speaker 140, a call button 150, a door controller 160, a door driving motor 170, an application access code 180, and the like. For reference, the components 110, 120, 130, 140, 150, 160, 170, 180 of the first access door opening and closing control device 100a shown in fig. 2a are only exemplary components for explaining the functions, operations, etc. of the first access door opening and closing control device 100a according to an embodiment of the present invention, and thus it is apparent that additional components (e.g., a power supply section, a communication section, an alarm section, a monitoring section, etc.) may be further provided.

The main body 110 constitutes a main body of the first access door opening and closing control device 100a, and may be adhered to at least a part of the area of the access door 500, or may be adhered adjacent to the access door 500. In addition, the body 110 may be made of metal or synthetic resin, and may be implemented such that the exposed surface has a predetermined color in order to improve visual effects, as exemplarily illustrated in fig. 2a, the shape thereof may be rectangular, but is not limited thereto.

Further, as exemplarily illustrated in fig. 2a, a camera 120, a bluetooth module 130, a speaker 140, a call button 150, an application access code 180, etc. may be buried or implemented in an exposed surface of the main body 110, the door controller 160 may be programmably embedded in the interior of the main body 110, and the door driving motor 170 may be disposed in an inner space of a wall of the access door 500 or in an inner space of a bathroom.

The camera 120 may be configured to capture a predetermined area of the front face toward which the first access door opening/closing control device 100a is directed. In the case where a user such as a child, an elderly person, or the like who does not have a smart phone uses a public washroom, or in the case where a temporary malfunction of the access door opening/closing control system 1000 occurs, the user can communicate with a responsible person (e.g., a monitoring person) of the integrated information center 200 by pressing the call button 150, the responsible person can visually confirm the sex of the user who accesses the public washroom through the camera 120, and can remotely control the open access door 500 only in the case where it is confirmed that the user is a female through the camera 120.

In the case where the sex of the user cannot be clearly determined only by the screen displayed by the camera 120 according to the additional embodiment of the present invention, the integrated information center 200 can further determine whether the user is male or female by analyzing the voice of the user. For this purpose, a predetermined voice guidance sentence (for example, "please say" until the east sea water and the white mountain dry up and wither' | ", etc.) may be output through the speaker 140.

Further, in the case where the person in charge of the comprehensive information center 200 such as early morning time is not present, the access door opening/closing control method according to the additional embodiment of the present invention judges the sex based on a predetermined algorithm (for example, a sex recognition deep learning algorithm based on an image or the like) from the face image photographed by the camera 120 while judging the sex by voice analysis, and generates an access door opening/closing control command allowing the access door to be opened only in the case where the sex judgment based on the face image and the sex judgment result by voice analysis are female, and transmits to the first access door opening/closing control device 100a.

The speaker 140 has not only a function of communicating with a monitor person of the integrated information center 200 but also a voice guidance function, and for example, the read result of the access door open encryption code 30 of the integrated information center 200 may send out an access permission or prohibition voice message such as "permit access", "prohibit access", or, in the case where the sex cannot be discriminated, may send out an identification error voice message such as "identification failure".

The call button 150 corresponds to a button that allows the user to communicate with the monitoring person of the integrated information center 200 when there is no user of the smart phone or when the system temporarily fails, and real-time communication between the monitoring person of the integrated information center 200 and the user can be achieved by pressing the call button 150. When the call button 150 is pressed, the monitoring person in the integrated information center 200 can confirm the user through the camera 120, and can talk with the user through the speaker 140 if necessary, and can permit the opening of the access door 500 only when the user is finally determined to be female.

For reference, the camera 120, the speaker 140, and the call button 150 are equivalent to supplementary means required for users such as children and elderly people without smartphones, and therefore the first access door opening/closing control device 100a according to another application example of the present invention may not include the camera 120, the speaker 140, and the call button 150.

The bluetooth module 130 is configured to be capable of bluetooth communication with the user terminal 300, whereby the entry and exit door opening encryption code 30 transmitted by bluetooth can be received at the user terminal 300. For example, if the user runs the access door opening/closing encryption code issuing application 20 (see fig. 4 and 5) and approaches within a predetermined distance (for example, 3M or the like) from the first access door opening/closing control device 100a, the user terminal 300 may be automatically connected to the first access door opening/closing control device 100a through bluetooth communication, and if the user clicks the access door opening request button, the access door opening/closing encryption code 30 may be issued from the application program operation server 600, and the issued access door opening/closing encryption code 30 may be transmitted from the user terminal 300 to the first access door opening/closing control device 100a through bluetooth communication.

The present invention is characterized in that the opening and closing of the public restroom entrance 500 is controlled based on the reading of the entrance and exit door opening encryption code 30, and a user (i.e., female user) can obtain the entrance and exit door opening encryption code 30 for entrance and exit of the public female restroom after the female user authentication using a predetermined application program, and in the following description, an application program providing a user with a service of issuing the entrance and exit door opening encryption code 30 for entrance and exit of the public restroom is referred to as an "entrance and exit door opening encryption code issuing application program".

The user can download the entry-opening encryption code issuing application 20 (refer to fig. 4 and 5) through an application download service of the android market (Play Store), the apple market (App Store), or the like, wherein the entry-opening encryption code issuing application 20 must be authenticated by himself when installed and operated, so that only female users can use the entry-opening encryption code issuing application 20, and for female user authentication using such application, a more detailed description will be given in fig. 3 below.

Alternatively, according to the additional embodiment of the present invention, even if a male downloads and installs the access door opening encryption code issuing application 20, the generation of the access door opening encryption code 30 can be prevented, or even if the access door opening encryption code 30 is generated for a male user, the sex information of the male can be contained in the issued access door opening encryption code 30, thereby fundamentally preventing the male from going into and out of a public place or a female restroom in a general building.

Therefore, when a female user wants to use the public washroom, by running the access door opening encryption code issuing application 20 downloaded in advance, the access door opening encryption code 30 can be easily obtained, and the public female washroom can be used more easily and safely as long as the user terminal 300 storing the obtained access door opening encryption code 30 is held close to the first access door opening/closing control device 100 a.

In connection with this, according to an additional embodiment of the present invention, an application access code 180 may be further provided in an area of the main body 110 where the bluetooth module 130 is disposed. For example, the application access code 180 may be a two-dimensional code (QR: quick Response) and may be composed of an android system QR code 181 and an apple system QR code 182, even in a state where the user does not download the access door open encryption code issuing application 20 in advance, by connecting with the application access code 180 provided on the first access door opening/closing control apparatus 100a disposed in the public washroom, the access door open encryption code issuing application 20 can be easily downloaded and used.

For reference, the access door opening encryption code 30 that is issued by running the access door opening encryption code issuing application 20 may include a plurality of codes to enhance security and prevent malicious use, and a more specific configuration of the access door opening encryption code 30 will be described in more detail in fig. 5 below.

The door controller 160 may be programmably embedded inside the main body 110 of the access door opening/closing control apparatus 100, and may be implemented as a processor (processor), a microprocessor (micro-processor), a controller (controller), a microcontroller (micro-controller), or the like, for example. The door controller 160 may control the opening and closing of the access door 500 based on the access door opening and closing control command generated and transmitted at the integrated information center 200 (more specifically, the access door control and operation management server 210) and through the door driving motor 170 electrically connected to the door controller 160 and mechanically connected to the access door 500.

The integrated information center 200 may generate an access door opening/closing control command based on the read result of the access door opening/closing encryption code 30 transmitted from the first access door opening/closing control device 100a, and may transmit the generated opening/closing control command to the first access door opening/closing control device 100a. As shown in fig. 2a, the integrated information center 200 according to the first embodiment of the present invention may be composed of an access control and operation management server 210 and an operation terminal 220, and for example, the integrated information center 200 may be operated with Software (SW) for access management of a public restroom.

The access door control and operation management server 210 may receive and read the access door opening/closing encryption code 30 transmitted from the first access door opening/closing control device 100a, may transmit the read result to the first access door opening/closing control device 100a, and may be communicably connected to and operated by the operation terminal 220 in the integrated information center 200. The access control and operation management server 210 recognizes information contained in the access opening encryption code 30 issued by the access opening encryption code issuing application 20 managed and operated by the application operation server 600, determines whether or not the secret code is a secret code issued by a normal access opening encryption code issuing application, whether or not the sex of the secret code issuer is female, whether or not date and time information contained in the secret code satisfies a preset valid use time (for example, 10 seconds, 15 seconds, 20 seconds, etc.), and generates an access opening/closing control command as a result of the determination, and sends the command to the first access opening/closing control device 100a.

The operation terminal 220 may be provided in the integrated information center 200, and the operation terminal 220 may be communicably connected with the access door control and operation management server 210 to be able to support the operator of the integrated information center 200 to operate and manage the access door opening and closing control based on the access door opening encryption code 30, and to support user confirmation through the camera 120, communication through the speaker 140, remote control of the first access door opening and closing control device 100a, and the like.

The user terminal 300 can be communicably combined with the application operation server 600, and can store or temporarily store the access door opening encryption code 30 issued by the access door opening encryption code issuing application 20. As described above, the user may download the access door opening encryption code issuing application 20 in advance through the application download service of the playstore, app Store, or the like using the user terminal 300, or may download the access door opening encryption code issuing application 20 from the access door 500 before using the application access code 180 embodied on the first access door opening/closing control apparatus 100 a.

For reference, the User terminal 300 may also be referred to as a subscriber unit, subscriber station, mobile terminal, remote station, remote terminal, mobile device, access terminal, wireless communication device, user agent, user device, or User Equipment (UE). An access terminal may be a cellular telephone, a cordless telephone, a session initiation protocol (SIP: session initialization Protocol) phone, a wireless local loop ((WLL: wireless Local Loop) station, a personal digital assistant (PDA: personal Digital Assistant), a handheld device having wireless connection capability, a computing device, or other processing device connected to a wireless modem.

The application program operation server 600 configured to receive the entry opening request from the user terminal 300 and to transmit the entry opening encryption code 30 to the user terminal 300 in response to the request may synchronize with the integrated information center 200 (more specifically, the entry control and operation management server 210) in real time, whereby the entry control and operation management server 210 can determine information on the entry opening encryption code 30 issued from the application program operation server 600.

Fig. 2b is a block diagram of an access door opening and closing control system 1000' according to a second embodiment of the present invention. As shown in fig. 2b, the access door opening and closing control system 1000' according to the second embodiment of the present invention may be configured to include a second access door opening and closing control device 100b, a user terminal 300, a communication network 400, an access door 500, an application operation server 600, and the like.

As described above, the access door opening and closing control system 1000' according to the second embodiment of the present invention can be applied to a female public restroom in a general building where an administrator of a government agency, school, company, or the like resides without remote management, and thus is different from the access door opening and closing control system 1000 shown in fig. 2a in that the integrated information center 200 is not provided.

As shown in fig. 2b, the second access door opening and closing control apparatus 100b according to the second embodiment of the present invention may be configured to include a main body 110, a bluetooth module 130, an application access code 180, a display 190, a controller 195, and the like. For reference, the description of the portions overlapping the description of the first access door opening/closing control device 100a described in fig. 2a will be omitted below.

The second access door opening and closing control system 1000' according to the second embodiment of the present invention can be more specifically applied to a washroom of a building that can cope with in time when a building manager resides or an emergency occurs, and in addition, can be more suitably applied to a building that operates a normal washroom and a secret code washroom separately on a floor-by-floor basis (for example, a building that operates a secret code washroom in one and five floors, a building that operates a normal washroom in two to four floors, etc.), a building that operates a normal washroom separately from a secret code washroom, etc., even in the same floor.

Therefore, in a case where the access door opening encryption code 30 cannot be used (for example, there is no smart phone, a malfunction of the second access door opening/closing control device 100b, or the like), a resident building manager may be inquired (in this case, a call button may be further provided), or a common toilet at another floor or another location may be used instead of the secret code.

The second access door opening/closing control apparatus 100b may decrypt and read the access door opening encryption code 30 received from the user terminal 300 through the bluetooth module 130, and may generate an access door opening/closing control command based thereon and include a controller 195 carrying a program for controlling the opening/closing of the access door 500. That is, the second access door opening and closing control apparatus 100b according to the second embodiment of the present invention may be implemented as an independent control type in which software for controlling the opening and closing of the access door of the female restroom in the general building (e.g., software for decrypting, reading, and thus executing the access door opening and closing control command) is programmably embedded without intervention of the comprehensive information center 200 shown in fig. 2 a.

In fig. 2b, for the convenience of understanding the present invention, the controller 195 constituting a part of the second access door opening and closing control apparatus 100b is illustrated as a block diagram, but the controller 195 is built in a chip or module manner inside the second access door opening and closing control apparatus 100b so as to be invisible from the outside. Further, the gate controller 160 according to the first embodiment of the present invention shown in fig. 2a and the controller 195 according to the second embodiment of the present invention shown in fig. 2b are collectively referred to as a control module. For reference, the application operation server 600 may log in and manage the position information of the public restroom provided with the second access door opening and closing control apparatus 100 b.

The display 190 may be disposed at an upper region of the second access door opening/closing control apparatus 100b, and may display information of whether or not to open the access door 500, which is determined based on the access door opening encryption code 30 read at the controller 195, information of a failure of reading the access door opening encryption code 30, information exceeding a valid time of the access door opening encryption code 30, status information of the second access door opening/closing control apparatus 100b, and the like.

For example, according to the result of the controller 195 reading the access door opening encryption code 30, information such as "allow access", "reject access", etc. may be displayed on the display 190, information such as "identification failure" may be displayed on the display 190 in the case of an abnormality of the apparatus, and information such as "excess use time" may be displayed on the display 190 in the case of exceeding the effective use time of the access door opening encryption code 30. In which information displayed on the display 190 may be displayed in korean, and in accordance with an additional embodiment of the present invention, in order to facilitate a foreign-style toilet user, both korean and english may be displayed on the display 190.

Further, the display 190 may be implemented as a touch-sensitive display, whereby a general building manager can easily control bluetooth communication settings with the access door 500, valid time settings of the access door open encryption code 30, etc. by touching the display 190. Further, according to the additional embodiment of the present invention, it is also possible to realize that various contents (for example, the building advertisement video, etc.) capable of attracting the user's interest or providing information, which may be stored in advance in a memory (not shown) of the second access door opening/closing control apparatus 100b and may be updated periodically or non-periodically, are played on the display 190, in addition to the recognition result of the access door opening/closing encryption code 30 displayed on the display 190.

For reference, the Display 120 may be implemented by a liquid crystal Display (LCD: liquid Crystal Display), a thin film transistor liquid crystal Display (TFT LCD: thin Film Transistor-Liquid Crystal Display), an Organic Light-Emitting Diode (OLED), a Flexible Display (Flexible Display), a three-dimensional Display (3D Display), or the like, but is not limited thereto.

Based on such an apparatus and system configuration, when the access door opening and closing code issuing application 20 is set and operated, in the case where a female user authenticated through the principal authentication process wants to use a public female restroom in a general building such as a government agency, school, company, etc., if the access door opening and closing code issuing application 20 is operated and comes close to within a predetermined distance (e.g., 3M, etc.) from the second access door opening and closing control apparatus 100b, synchronization can be achieved while the secret code 31 and the date/time code 33 are transmitted in bluetooth form from the application operation server 600 to the second access door opening and closing control apparatus 100b through the user terminal 300.

For reference, the bluetooth communication connection of the second access door opening and closing control apparatus 100b may be set to react only to the bluetooth signal of the user terminal 2300 that runs the access door opening encryption code issuing application 20 within a predetermined distance (e.g., 3M, etc.).

Although not explicitly shown in fig. 2a and 2b, the application operation server 200 according to the present invention may include a storage unit that may store user authentication issuing information regarding the access door opening encryption code issuing application 20, information regarding the issued access door opening encryption code 30, and the like.

For reference, as known to those skilled in the art, the storage part of the application program operation server 200 may be implemented as a Hard Disk Drive (HDD), a Read Only Memory (ROM), a random access Memory (RAM: random Access Memory), an electrically erasable programmable Read Only Memory (EEPROM: electrically Erasable and Programmable Read Only Memory), a Flash Memory (Flash Memory), a Compact Flash (CF: compact Flash) card, a Secure Digital (SD) card, a Smart Media (SM) card, a Multimedia (MMC) card, or a Memory Stick (Memory Stick) or the like, which can input and output information, or may be replaced with a web page storage (web storage) device that performs a storage function on the internet.

Fig. 3 is a conceptual diagram for explaining an authentication procedure of a female user for use of the access door opening encryption code issuing application 20 according to an embodiment of the present invention.

The user of the user terminal 300 may download the access door opening encryption code issuing application 20 in advance through an application download service of a Play Store, an App Store, or the like, or may download the access door opening encryption code issuing application 20 on the spot in public with the application access code 180 installed in the access door opening/closing control apparatuses 100a, 100 b.

The entry and exit opening encryption code issuing application 20 is downloaded from the application store server 800 to the user terminal 300 according to the request of the user terminal 300, and when the entry and exit opening encryption code issuing application 20 is run, a request for principal authentication may be received from the application operation server 600, and the request for principal authentication may be sequentially transmitted to the carrier server 700.

The carrier server 700, which is an operation server of a carrier providing a wired/wireless communication service to the user terminal 300, may include all of the respective servers of a plurality of carriers, and the carrier server 700 may respond to a request for principal authentication received from the user terminal 300, so that the result of principal confirmation may be transmitted to the application operation server 600 and the user terminal 300. For reference, the user information at the time of joining the communication service is retained in the carrier server 700, and thus, the carrier server 700 may retain the sex information of the user who transmits the principal authentication request for use authentication of the entry-exit open encryption code issuing application 20.

If the result of the principal confirmation is female, the application operating server 600 may issue a principal confirmation certificate (certificate) and provide it to the user terminal 300, whereby the user terminal 300 having received the principal confirmation certificate may obtain the use authority of the exit-entrance-opening encryption code issuing application 20.

For reference, according to an embodiment of the present invention, the user authentication program shown in fig. 3 may be performed only once initially when the access door opening encryption code issuing application 20 is downloaded, or according to another embodiment of the present invention, the access door opening/closing control system 1000, 1000' may be implemented to further set a certification validity period (for example, one year, etc.) and to re-perform the authentication program when the certification validity period expires.

In the case where each user initially performs user authentication only once, in the case where a user who owns a plurality of smartphones wants to change the smartphones that obtain the use authority of the access door opening encryption code issuing application 20, the application operation server 200 according to the additional embodiment of the present invention may be further configured to give the new smartphones the use authority of the access door opening encryption code issuing application 20 after releasing the use authority of the existing smartphones, and may restrict authorized use also for prepaid phones or the like that are difficult to ensure the user's reliability.

Fig. 4 is a conceptual diagram illustrating a scenario in which an authenticated female user opens an access door of a public restroom using the received access door opening encryption code 30, according to one embodiment of the present invention.

The female user may obtain the access door opening encryption code 30 for the opening of the access door 500 of the public female through the access door opening encryption code issuing application 20, and if the user runs the access door opening encryption code issuing application 20 and the user terminal 300 approaches within a predetermined distance (e.g., 3M, etc.) from the access door opening/closing control devices 100a, 100b, the user terminal 300 and the access door opening/closing control devices 100a, 100b may be automatically connected through bluetooth, and the access door opening encryption code 30 obtained by clicking the access door opening request button may be transmitted from the user terminal 300 to the access door opening/closing control devices 100a, 100b (e.g., refer to (a) of fig. 4).

Wherein, according to the additional embodiment of the present invention, when the entry-opening encryption code issuing application 20 is run in a state where the bluetooth function of the user terminal 300 is disabled, the entry-opening encryption code issuing application 20 may provide the user terminal 300 with a guide for activating bluetooth (e.g., expose a request/confirm screen for activating bluetooth to a display of the user terminal 300, etc.).

The access door opening/closing control device 100a, 100b that receives the access door opening/closing encryption code 30 from the user terminal 300 (i) in the case of the first embodiment, the first access door opening/closing control device 100a transmits the received access door opening/closing encryption code 30 to the integrated information center 200, receives an access door opening/closing control command generated in the integrated information center 200 through decryption and reading of the access door opening/closing encryption code 30, and executes the access door opening/closing control command received from the integrated information center 200, or (ii) in the case of the second embodiment, the second access door opening/closing control device 100b may decrypt and read the access door opening/closing encryption code 30 using the controller 195 programmed for decryption and reading of the access door opening/closing encryption code 30, and generates and executes the access door opening/closing control command based thereon.

In the case where the contents of the access door opening/closing control command received from the integrated information center 200 or the access door opening/closing control command generated by the second access door opening/closing control device 100b itself satisfy the access door opening conditions, the access door opening/closing control devices 100a, 100b may execute the access door opening/closing control command so that the access door 500 of the public restroom can be opened only when all the conditions are satisfied, i.e., (i) the secret code 31 is identical, (ii) the information of the sex code 32 is female, (iii) the effective use time generated according to the date/time code 33 (i.e., if any one of the three code conditions is not satisfied).

Alternatively, in the case where the contents of the access door opening/closing control command received from the integrated information center 200 or the access door opening/closing control command generated by the second access door opening/closing control device 100b itself do not meet the access door opening condition, for example, in the case where the secret code 31 is read as a falsified access door opening encrypted code issued not by the access door opening encrypted code issuing application 20 but by a falsified application or the like, in the case where the sex of the requesting user is not female, in the case where the valid use time of the secret code is exceeded, or the like, the access door opening/closing control devices 100a, 100b may execute the access door opening/closing control command such that the access door 500 of the public restroom is not allowed to be opened.

In connection with this, according to another embodiment of the present invention, if the predetermined available time (or effective use time) further defined in the date/time code of the access door opening encryption code 30 is exceeded, it may be implemented that the access door opening encryption code 30 is automatically deleted in the user terminal 300, and thus, in a state where the predetermined effective use time is exceeded, it is impossible to transmit the access door opening encryption code 30 from the user terminal 300 to the access door opening/closing control devices 100a, 100 b.

In addition, according to the additional embodiment of the present invention, if the access door opening encryption code 30 is deleted due to the exceeding of the valid use time, the user terminal 300 may be provided with a re-request interface of the access door opening encryption code 30 while notifying the user that the access door opening encryption code 30 is deleted (for example, a voice notification or a text notification that the code has been deleted).

As described above, according to the present invention, the user terminal 300 storing the access door opening/closing encryption code 30 in the form of a digital signal can open the access door 500 only limitedly to the female user as long as it is within a predetermined distance from the access door opening/closing control devices 100a, 100b, thereby (i) making it possible to make the secret code recognition rate not affected by environmental factors such as temperature, humidity, light, dust, etc., (ii) making it possible to facilitate diversification, miniaturization, and slimness of the access door opening/closing control devices 100a, 100b, and (iii) making it possible to further reduce the manufacturing cost of the access door opening/closing control devices 100a, 100 b.

Fig. 5 is an exemplary diagram of an access door opening encryption code issuing application 20 and an access door opening encryption code 30 according to an embodiment of the present invention. As shown in fig. 5, the entry and exit door opening encryption code 30 according to an embodiment of the present invention may be configured to include a secret code 31, a sex code 32, and a date/time information code 33.

Among the plurality of codes included in the access door opening encryption code 30, the secret code 31 serves as a code for screening only the authenticated (i.e., issued by the genuine access door opening encryption code issuing application 20) access door opening encryption code 30, and corresponds to a code for preventing unauthorized intrusion of a male through a fake or similar application-generated access door opening encryption code into a crime such as a female restroom. For this purpose, the secret code 31 may include a unique code composed of a mixed character, a symbol, or the like given by the application program operation server 600, and the encrypted information of such secret code 31 can be generated and stored only in the application program operation server 600.

Accordingly, in the case where such a secret code 31 does not exist in the access door opening encryption code 30 transmitted from the user terminal 300 or is inconsistent with the secret code generated in the application operation server 600 even if the secret code 31 is provided, (i) an access door opening/closing control command that does not allow the access door 500 to be opened may be generated and transmitted to the first access door opening/closing control device 100a (in the case of the first embodiment), or (ii) an access door opening/closing control command that does not allow the access door 500 to be opened may be generated by the controller 195 programmed in the second access door opening/closing control device 100b (in the case of the second embodiment).

For reference, such secret code 31 included in the access door opening encryption code 30 issued by the application program operation server 600 in response to the access door opening request from the user terminal 300 may be (i) a code that may be implemented as a fixed value, or (ii) may be updated at predetermined periods (e.g., daily, weekly, monthly, etc.) or aperiodically, or (iii) may be implemented as a new secret code each time the access door opening encryption code 30 is issued, and change information of such access door opening encryption code 30 may be synchronized with the integrated information center 200 or the second access door opening/closing control apparatus 100 b.

Alternatively, according to the additional embodiment of the present invention, the application operation server 600 and the second access door opening/closing control device 100b may not be connected by wireless communication (for example, 5G, LTE, etc.), and in this case, if the user terminal 30 running the access door opening/closing code issuing application 20 approaches within a predetermined distance from the second access door opening/closing control device 100b, the change information (for example, the set secret code 31 and the date/time code 33) of the access door opening/closing code 30 may be synchronized by bluetooth communication.

Further, among the plurality of codes included in the access door opening encryption code 30, the sex code 32 corresponds to a code for proving that the sex of the user who obtained the access door opening encryption code 30 belongs to a female. As described in fig. 3, in the process of downloading the access door opening encryption code issuing application 20 according to the present invention, although the user gets a certification for certifying it as a female, by further incorporating the sex code 32 for certifying that the sex of the user is female into the access door opening encryption code 30, the security and reliability of the secret code can be further improved, and in the case where it is necessary to control the access door of the male-dedicated access area, it can be easily implemented by adding the male code instead of the female code.

Accordingly, the access door control and operation management server 210 or the second access door opening/closing control device 100b of the integrated information center 200 can generate and execute an access door opening/closing control command that does not allow the access door 500 to be opened, when such a sex code 32 is not present in the access door opening/closing encryption code 30 transmitted from the user terminal 300 by bluetooth or when the sex is determined to be a male even if the sex code 32 is provided.

Further, among a plurality of codes included in the access door opening encryption code 30, the date/time information code 33 may be used to identify the available valid time of the obtained access door opening encryption code 30. For reference, the date information and time information included in the date/time information code 33 corresponds to information automatically received by the global positioning system (GPS: global Positioning System), and thus accuracy is very high, and such date/time information is synchronized between the access control and operation management server 210/the second access control device 100b and the application operation server 600 (i.e., the date/time information in the access control and operation management server 210/the second access control device 100b is identical to the date/time information in the application operation server 600), and thus user inconvenience due to a time difference in the integrated information center 200/the second access control device 100b and the application operation server 600 can be fundamentally prevented.

Further, the application operating server 600 according to an embodiment of the present invention may set in advance a valid use time of the access door opening encryption code 30 in response to the access door opening request from the user terminal 300, so that the valid use time of the access door opening encryption code 30 may be a fixed value (e.g., 10 seconds, 15 seconds, etc.) when generating the access door opening encryption code 30 for accessing a female restroom in a public place such as a park, square, or a general building such as a government agency, school, etc.

As described above, by generating and issuing the access door open encryption code 30 and prohibiting the use of the access door open encryption code 30 after exceeding a predetermined time, it is possible to effectively prevent the situation where the access door open encryption code 30 is improperly used in a copy, store, or the like, or sent to a third party for illegal use.

Wherein, according to an additional embodiment of the present invention, the step of determining whether the user terminal 300 requesting the issuance of the access door opening encryption code 30 is a loss-reporting terminal may be further included. In order to prevent a man from picking up and maliciously using a smart phone lost by a woman, according to an additional embodiment of the present invention, it is possible to further confirm whether the user terminal 300 is lost or not in the application operation server 600, and in the case where the user terminal 300 is confirmed to be a lost terminal, by causing the application operation server 600 to further generate a telephone number and lost terminal information in the entry opening encryption code 30 generated by the user terminal, it is possible to generate and execute an entry opening/closing control command that does not allow the entry 500 to open even if the above three code conditions are satisfied (i.e., (i) the entry opening encryption code 30 is made equivalent to a normal entry opening encryption code 30 issued by the entry opening encryption code issuing application by the identified secret code 31), (ii) the sex of the user who issued the entry opening encryption code 30 is equivalent to a woman, and (iii) the valid time condition of the entry opening encryption code 30).

In this case, the integrated information center 200/second access door opening and closing control apparatus 100b according to an embodiment of the present invention may be further communicably combined with an organization such as a police department, and if a request for access to a female restroom using a loss-of-available user terminal is confirmed, the position information of the access door opening and closing control apparatus 100a, 100b and an image captured by the camera 120 (or an image captured by a surrounding CCTV or the like) are immediately transmitted to the police department or the like, so that a considerable contribution can be made in terms of capturing a potential criminal and reducing crimes.

Further, according to an additional embodiment of the present invention, the position information of the public restroom to which the access door opening and closing control system 1000, 1000' according to the present invention is applied can be provided based on the position of the user.

For example, the service provided by the access door opening and closing code issuing application 20 according to the present invention may provide the user who needs to search for the public restroom location with the location information of the public restroom provided with the access door opening and closing control devices 100a, 100b according to the present invention based on the current location of the user terminal 300, and for this purpose, may be further provided with an interface for searching for the public restroom, and the provided public restroom information may be represented as a map (map) based service, for example.

As described above, the access door opening and closing control apparatuses 100a, 100b according to an embodiment of the present invention have IP addresses in a digital manner, and thus the application program operation server 600 can grasp and hold the position of each of the plurality of access door opening and closing control apparatuses 100a, 100b based on the IP addresses of the access door opening and closing control apparatuses 100a, 100 b. Therefore, the user can confirm the position of the public restroom where the access door opening/closing control devices 100a and 100b are provided, centering on the current position of the user, and thus the user can easily determine the safe public restroom located around the user.

In addition, the application operation server 600 of the present invention may provide facility information (e.g., cleanliness, year of completion, etc.) of the public restroom through the access door opening encryption code issuing application 20, and may further provide an evaluation interface to the user terminal 300 so that the user may perform satisfaction evaluation on the public restroom and may also provide predetermined activities (e.g., points, etc.) to the user having excellent participation.

In addition, in fig. 5, the embodiment in which the access door opening/closing encryption code 30 is configured to include the secret code 31, the sex code 32, and the date/time code 33 and to control the access door opening/closing of the public restroom is described as an example, but according to the additional embodiment of the present invention, the access door opening/closing control system 1000, 1000' according to the present invention can be extended to be applied to the access management of the specific authorizer control area by including additional information such as the name, the date of birth, the telephone number, and the like in the access door opening/closing encryption code 30.

Fig. 6a is a flowchart illustrating an access door opening and closing control method of a public washroom according to a first embodiment of the present invention, and fig. 6b is a flowchart illustrating an access door opening and closing control method of a public washroom according to a second embodiment of the present invention.

Referring to fig. 2a and 6a together, according to the entrance/exit door opening/closing control system 1000 applicable to female restrooms scattered in wide areas and requiring remote management by an administrator, such as parks and squares, first, an entrance/exit door opening request can be transmitted from the user terminal 300 to the application operation server 600 by a user who wants to use the public restrooms (S11). Here, the access request may be transmitted to the application operation server 600 by the user clicking an access request button displayed on the display of the user terminal 300, and at this time, when the access code issuing application 20 is downloaded and installed, a certificate obtained by personal authentication may be transmitted to the application operation server 600 together with the access request.

In response to the received access door opening request, the application program operation server 600 may generate a digital code composed of the secret code 31, the sex code 32, and the date/time code 33 (S12), and generate the access door opening encryption code 30 by encrypting it (S13).

The generated access door opening encryption code 30 may be transmitted to the user terminal 300 again (S14), and if the user who has obtained the access door opening encryption code 30 approaches within a predetermined distance (e.g., 3M, etc.) from the first access door opening/closing control apparatus 100a, the user terminal 300 and the first access door opening/closing control apparatus 100a are automatically connected through bluetooth so that the access door opening encryption code 30 may be transmitted from the user terminal 300 to the first access door opening/closing control apparatus 100a through bluetooth (S15).

The first access door opening/closing control device 100a, which receives the access door opening/closing encryption code 30 from the user terminal 300 through bluetooth, may retransmit the access door opening/closing encryption code 30 to the integrated information center 200, more specifically, may transmit the access door opening/closing encryption code 30 to the access door control and operation management server 210 (S16), and the integrated information center 200 may generate the access door opening/closing control command by decrypting (S17) and reading (S18) the received access door opening/closing encryption code 30.

The generated access door opening/closing control command may be transmitted again from the integrated information center 200 to the first access door opening/closing control device 100a (S19), and the first access door opening/closing control device 100a may open the access door 500 connected to the first access door opening/closing control device 100a by wired or bluetooth by executing the access door opening/closing control command (S20) (S21).

Referring to fig. 2b and 6b together, according to the entrance/exit door opening/closing control system 1000' applicable to female restrooms in general buildings such as government offices, schools, companies, etc. where a general manager resides without remote management, first, an entrance/exit door opening request may be transmitted from the user terminal 300 to the application operation server 600 by a user who wants to use a public restroom (S31). Here, as described above, the access request may be transmitted to the application operation server 600 by the user clicking the access request button displayed on the display of the user terminal 300, and at this time, when the access code issuing application 20 is downloaded and installed, the authentication ticket obtained by the personal authentication may be transmitted to the application operation server 600 together with the access request.

In response to the received access door opening request, the application program operation server 600 may generate a digital code composed of the secret code 31, the sex code 32, and the date/time code 33 (S32), and generate the access door opening encryption code 30 by encrypting it (S33).

The generated access door opening encryption code 30 may be transmitted to the user terminal 300 again (S34), and if the user who has obtained the access door opening encryption code 30 approaches within a predetermined distance (e.g., 3M, etc.) from the second access door opening/closing control apparatus 100b, the user terminal 300 and the second access door opening/closing control apparatus 100b are automatically connected through bluetooth, so that the access door opening encryption code 30 may be transmitted from the user terminal 300 to the second access door opening/closing control apparatus 100b through bluetooth (S35).

The second access door opening/closing control device 100b that receives the access door opening/closing encryption code 30 from the user terminal 300 by bluetooth can be realized as an independent control type controller 195 by using a program (or software) incorporated therein for controlling the opening/closing of the access door of the public restroom, and generates an access door opening/closing control command by decrypting (S36) and digital code interpretation (S37) the received access door opening/closing encryption code 30. Then, the second access door opening/closing control device 100b executes the generated access door opening/closing control command (S38), and thereby opens the access door 500 connected to the second access door opening/closing control device 100b by wire or bluetooth (S39).
